IMPROVEMET IN BRICK-MOULDS.

'lhe Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, STEPHEN INMAN, of Rockford, in thc county of Winnebago, and State of Illinois, have invented a new and 'useful Improvement in Brick-Mould; and I do hereby declare that the following is a full and exact description of the same, reference 'being had to the accompanying drawings, and to the letters of reference marked thereon.

' This invention relates to that class of brick-moulds which is provided with followers in its divisions, operated by means of levers; and

It ycinisists mainly in the combination of lon gitudiu al turning rods, with transverse bars, by means of which the followers are operated.

It further consists, also, in the-construction of the followers employed. Y

The-details of construction and manner of operation will be fully described hereinafter.

In the drawings Iigure 1 is a plan view of my invention.`

v Figure 2, a sectional elevationthrough line x at.

Figure 3, a sectional elevation through line y'y.

Figures 4 and 5 are views ofthe followeru To enable others skilledliu the art to make anduse my invention, I will n ow proceed to describe ful-ly its construction and operation.

A represents a brick-mould of the ordinary construction, which is provided with the 'loose bottoms or followers a a' a, fitting snugly. into its divisions, as shown in figs. 1 and 3.

r .To operate these followers, I attach to their lower sides, at each end, the rods b b, having slotted ends,

as shown, which are secured in place by the headed pin b1.

These rods extend transversely across the mould, and are rigidly attached to the longitudinal bars or rods B B on each side, which latter are held in place by bands c c c, as 4shown in gs. 2, 3, and 4.

The ends of the rods B B are bent and united, to

'form thelfandles b2, the attachment between the two being such as to permit the necessary play when the handles are. depressed.

Other methods of attaching the rods b b to the vbottoms may be employed. A different form is shown in figs. 2 and 3, in which the rods are rigidly attached to' vibrating pins.A j

The arrangement of the rods B B may also be varied, if desired. A single rodmay be used, placed in' the centre of the mould, and operated by a lever.

In iigs. 2 and 3 is shown a-detached view of my improved follower.

I) represents a perforated Vmetallic plate, with la flange, d, which is covered with cloth, or other suitable material, and provided with leather on its edges.

E represents a wooden back, which is perforated, to correspond with the plate D, and slotted, to permit the movement of the vibrating pins d. This backing E is attached to the plate D by means of the T- shaped pin in the centre of the plate, which projects through the backing, and is turned across the opening.

The operation of my improved brick-mould is follows:

It is rstplaced in the machine and filled, in the ordinary manuel'. [t is then removed to the ground, and turned over. The hands of the operator are now guided over the. levers and the cleats at the ends of the mould, and, as the latter is lifted, the handles b2 are depressed, and through the medium of the rods l B l), the bricks are simultaneously expelled from the mould.

By this apparatus, I am enabled to use harder clay and obtain better brick with perfect edges.

Withthe ordinary mould, it often happens, that when one brick is loosened from the mould, another adheres, and the falling brick is consequently injured in shape.

L 'lhe combination of the longitudinal turuing.

rods B with the transverse rods l) b, when operated as described, for the purpose set forth.

2. The combina-tion of the mould A, followers tra a, rods l1 b B B, and handles if, in the manner described, for the purpose set forth.

3. The follower described, consisting of the face D,

with vibrating pins d', in combination with the slotted backing E, as described, for the pnrpose'set forth.

This specification signed and witnessed, this 25th day of September, 1869.

STEPHEN INMAN.
